A technique may involve coupling a container of heat transfer fluid to an input and removing moisture from the heat transfer fluid via a molecular sieve. A pressure source is configured to push the heat transfer fluid out of the container and through the molecular sieve. Subsequent to removing the moisture from the heat transfer fluid, the technique involves separating, via an orifice coupled to a tank, the heat transfer fluid into liquid and gas particles within the tank and removing, via a vacuum coupled to the tank, the gas particles from the tank.

The technique may be performed by a portable device that houses the various components used to condition and delivery the thermal fluid.

Description

FIELD

[0001] The present disclosure relates generally to techniques for thermal fluid conditioning, and more particularly to a portable thermal fluid conditioning system that can condition and supply liquid to different types of fluid systems.

BACKGROUND

[0002] A heat transfer fluid is a gas or liquid that can enable heat transfer by serving as an intermediary in cooling on one side of a process, transporting and storing thermal energy, and heating on another side of a process. Heat transfer fluids are utilized within various applications, including industrial processes that involve heating or cooling.

[0003] The liquid phase of some heat transfer fluids can have useful heat transfer properties over a wide temperature range. For instance, some liquid phase heat transfer fluids can display useful heat transfer properties over a range of approximately negative 90 degrees Celsius to positive 200 degrees Celsius. As heat transfer fluid ages, the formation of low and high boiling compounds may result, which may require conditioning before use within a thermal fluid system. To condition the heat transfer fluid, low-boiling compounds can be vented from the system as necessary to a safe location away from users and sources of ignition while the high-boiling compounds are often very soluble in the fluid. Significant overheating or fluid contamination during heat transfer fluid conditioning can accelerate decomposition and may result in increased high-boiler and solids concentrations. In other applications, dissolved and entrained gases pose as issues in the dynamic operation of fluidic systems. To mitigate bubble generation as a result of these dynamic processes over a wide temperature range, heat transfer fluid can require fluid conditioning.

DETAILED DESCRIPTION

[0009] Disclosed examples will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all of the disclosed examples are shown. Indeed, several different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art.

[0010] Heat transfer fluid can require conditioning to remove moisture, solid particles, and entrained and dissolved gases to prepare the fluid for use in various types of thermal management systems, such as within vehicles, spacecraft, and industrial applications, etc. Existing heat transfer fluid conditioning solutions typically involve multiple steps performed by physically separate equipment, which can create the potential for recontamination via contact with air during each individual process and during the transitions from process to process between the different equipment. In addition, supplementary equipment is then typically needed to transfer the conditioned heat transfer fluid into the thermal management system.

[0011] Examples presented herein relate to techniques for thermal fluid conditioning and delivery that avoid the drawbacks associated with existing heat transfer fluid conditioning processes. In particular, example systems, devices, and methods described herein enable conditioning and delivery of heat transfer fluid into a thermal management system without requiring multiple steps performed by physically separate equipment. Rather, disclosed techniques can be implemented by a singular device or system that can independently condition heat transfer fluid and deliver the fluid into a thermal management system without the need for additional equipment to facilitate the transfer into the thermal management system. The different devices and systems can involve components connected that enable efficient conditioning and delivery of liquid into a fluid system without requiring transfer of the fluid between physically separate components that require user connections.

[0012] By way of an example, a disclosed system can be configured to hook up to a standard container of heat transfer fluid (e.g., a 55 gallon transport drum of a hydrocarbon) and convey the fluid through a series of valves, hoses, and tubing prior to delivery into a destination thermal management subsystem. The system prepares the heat transfer fluid for the destination thermal management system via a vacuum pump system and dry gas delivery system. The system also conditions the heat transfer fluid by removing moisture (e.g., via a molecular sieve) and entrained and dissolved gases within the fluid via an orifice aeration process before supplying the conditioned heat transfer fluid to the thermal management system. As such, the system's configuration utilizes the vacuum system and dry gas delivery system to perform both the purification as well as the transfer into the thermal management system, which removes the need for additional physically separate equipment. In addition, the mechanical structure of the system can include wheels to enable the system to change positions near the receiving thermal management system (e.g., a machine or a vehicle, such as a spacecraft).

[0013] In some implementations, valves, the vacuum pump, and other components within the system can be controlled via a computing device. The computing device may receive user instructions and responsively perform disclosed conditioning techniques to prepare and supply the heat transfer fluid into the thermal management system. The computing device can also operate to automatically perform disclosed operations to condition heat transfer fluid for delivery into a thermal management system. In other implementations, valves, the vacuum pump, and other components can be manually controlled by a user. For instance, the user can open and close valves to control the movement of the heat transfer fluid through the system. As such, the system may include gauges, scales, and other features that enable the user to review states of components within the system. For instance, a scale may measure the weight of conditioned liquid ready for delivery into a thermal management system.

[0014] Disclosed systems and devices can also receive fluid from a thermal management system. For instance, the device can be positioned by a thermal management system, which may drain used heat transfer fluid into the device. The device can prepare the used fluid for disposal and/or may recondition the fluid in some instances.

[0015] Referring now to the Figures, Figure 1 illustrates a block diagram of a system 100 for conditioning and supplying liquid to a fluid system. In the example, the system 100 includes an input 102, heat transfer fluid 104, a molecular sieve 106, a pressure source 108, a tank 110, an orifice 112, a vacuum pump 114, an output 116, housing structure 118, valves 120, filters 122, a cold trap 124, a scale 126, a scale display 128, and a vacuum gauge display 130. The elements of the system 100 are shown connected via connection 132. In other examples, the system 100 can have a different configuration, which may involve more or fewer components overall. For instance, the system 100 may also include a computing device 134 in some example implementations. In addition, the configuration and size of individual components within the system 100 can vary based on the use of the system 100.

[0016] The system 100 can represents a compact and portable system configured to condition and deliver heat transfer fluids directly to various types of thermal management systems. For instance, the system 100 can be used to condition and subsequently supply heat transfer fluids 104 to thermal management systems on spacecraft, vehicles, and within various industrial applications. The system 100 can be stationary in some examples, such as at a location that is accessible by thermal management systems (e.g., within a manufacturing setting). In other examples, the housing structure 118 of the system 100 can include wheels and/or another type of movement mechanism that allows the system 100 to change locations. This way, the system 100 can be repositioned by a spacecraft or another source selected to receive the conditioned liquid produced from the heat transfer fluid 104.

[0017] The input 102 can enable heat transfer fluid 104 to be initially connected to the system 100 for subsequent conditioning and delivery. In the example, the input 102 is configured to couple to a container containing the heat transfer fluid 104. For instance, the container of heat transfer fluid 104 can be a transport drum of hydrocarbon liquid (e.g., a synthetic hydrocarbon based liquid). As such, the input 102 can include one or more hoses and/or tubes (represented by connection 132), which can extend into the container and access the heat transfer fluid 104. As such, the type and quantity of heat transfer fluid 104 can vary within examples and may depend on the device or system using the conditioned heat transfer fluid 104 produced by the system 100. In some cases, the heat transfer fluid 104 can be generic heat transfer fluid (e.g., an off-the-shelf fluid).

[0018] The system 100 also includes a molecular sieve 106 that is configured to remove moisture from the heat transfer fluid 104. To enable the molecular sieve 106 to remove the moisture, the system 100 includes a pressure source 108 that can supply pressure to push the heat transfer fluid out 104 of its container and through the molecular sieve 106. In some example examples, the pressure source 108 is a tank containing an inert gas, such as helium, neon, argon, krypton, xenon, or radon. The pressure source 108 can differ in other examples. As such, the pressure source 108 can connect to the container of heat transfer fluid 104 via one or multiple tubes (represented by connection 132) that enable gas pressure to flow into the container to push out the heat transfer fluid 104 and through the molecular sieve 106. This way, the molecular sieve 106 can remove moisture of the heat transfer fluid 104 and prepare the heat transfer fluid 104 for further conditioning within the system 100. The pressure source 108 can provide different ranges of pressure within examples. For instance, the pressure source 108 can supply low pressure (e.g., less than 100 pounds per square inch (PSI), medium pressure (e.g., 500 to 2000 PSI), or high pressure (e.g., greater than 2000 PSI). Other pressure ranges can be used.

[0019] The configuration of the molecular sieve 106 can vary within examples. In practice, the molecular sieve 106 can be a material with pores, which may be uniform in size. The pores can have diameters that are similar in size to small molecules, which allows the moisture to be removed from the heat transfer fluid 104. In particular, contaminants and moisture cannot flow through the pores, which results in the molecular sieve 106 removing moisture while allowing a remainder of the heat transfer fluid 104 to flow through. In some examples, multiple molecular sieves can be used. In such cases, the molecular sieves can be redundant and/or different in configuration to further enhance moisture removal from the heat transfer fluid 104 by increasing the quantity of pores that the heat transfer fluid 104 experiences. In some cases, different materials are used within the molecular sieve 106 or multiple molecular sieves 106, which can remove moisture through the application of different sized pores.

[0020] After the molecular sieve 106 removes moisture from the heat transfer fluid 104, the system 100 can then cause the heat transfer fluid 104 to pass through an orifice 112, which is coupled to the tank 110. In practice, the orifice 112 is configured to separate the heat transfer fluid 104 into liquid and gas particles within the tank 110. The pressure source 108 can push the heat transfer fluid 104 through tubes connected to the orifice 112 to enable the orifice 112 to separate the heat transfer fluid 104 into liquid and gas particles. In some examples, the orifice 112 can include various types of agitation that further separate the heat transfer fluid 104 into liquid and gas particles. For instance, the orifice 112 can include an aerometer, metal mesh matrix, and/or sponges. In some examples, the diameter can be 0.01 to 0.02 inches for the orifice, which can vary in other cases. The diameter of the orifice 112 can influence the rate at which the heat transfer fluid 104 can be separated into liquid and gas within the tank 110.

[0021] The separation of the heat transfer fluid 104 into liquid and gas particles by the orifice 112 allows the vacuum pump 114 to remove the gas particles from the tank 110 and other components within the system 100. This removal of gas particles can take out contaminants from the heat transfer fluid 104 thereby producing a conditioned liquid that can be used within a fluid system. In practice, the vacuum pump 114 is connected to the tank 110 and can remove gases from the tank 110 to enable the orifice 112 to separate the heat transfer fluid 104 into gas and liquid. The vacuum pump 114 can regulate the pressure within the system 100 and enable the pressure source 108 to supply pressure that moves the heat transfer fluid 104 through the different components.

[0022] The configuration of the orifice 112 can differ within the examples. The vacuum pump 114 can be controlled by a user in some examples. For instance, the user can power on and power off the vacuum pump 114. In other examples, the vacuum pump 114 is controlled via computing device. The computing device may power on the vacuum pump 114 in response to other aspects within the system 100, such as the connection of the heat transfer fluid 104 to the input 102. In some implementations, the vacuum pump 114 can be operated at different settings, such as a high power setting and a low power setting. In addition, the type of the vacuum pump 114 can differ in some implementations. The vacuum pump 114 can be a dry scroll pump.

[0023] After the vacuum pump 114 removes the gas particles from the tank 110, the system 100 is configured to supply the liquid within the tank 110 into a thermal management system via the output 116 of the system 100. The output 116 may include one or more tubes that extend into the tank 110 and also connect to the receiving thermal management system, such as a spacecraft or another type of system or device that uses the conditioned liquid produced from the heat transfer fluid 104.

[0024] In addition, the system 100 includes a housing structure 118, which represents a mechanical structure for the system 100. In some examples, the housing structure 118 is configured with wheels to enable the system 100 to be moved around, such as to a location nearby the destination thermal management system. The different components of the system 100 are positioned on and connected to together relative to the housing structure 118 to allow mobility of the system 100.

[0025] As further shown in Figure 1, the system 100 can also include other components, such as valves 120, filters 122, a cold trap 124, a scale 126, a scale display 128, and a vacuum gauge display 130. The valves 120 are devices that can regulate and control the flow of a fluid (e.g., gases, liquids, fluidized solids, or slurries), by opening, closing, or partially obstructing various passageways (represented by connection 132). The system 100 can incorporate valves 120 at various positions to regulate and control pressure from the pressure source 108 and/or to control the flow of the heat transfer fluid 104 through the system 100. In some examples, the valves 120 are manually adjusted via a user. For instance, the user may open, close, or partially open/close the valves 120 to enable the system 100 to condition and supply the heat transfer fluid 104. A computing device (e.g., computing device 134) may also control the valves 120 in some implementations. The valves 120 can also include pressure release valves that can allow gas pressure to be vented from the system 100. Similarly, the system 100 can also include one or more filters 122, which can be positioned at various locations relative to other components within the system 100. The filters 122 can separate solids from fluids (liquids or gases) by serving as a medium through which only the fluid can pass.

[0026] The cold trap 124 can be coupled to and provide protection for the vacuum pump 114. The cold trap 124 can condense the permanent gases into a liquid or solid and can prevent vapors from entering the vacuum pump 114 where they would condense and contaminate it. The cold trap can be a device that condenses vapors except the permanent gases into a liquid or solid.

[0027] The scale 126 can be connected to the tank 110 and enable the weight of the tank 110 to be measured and displayed on the scale display 128. This way, users can view how much liquid volume is positioned within the tank 110. Similarly, the settings of the vacuum pump 114 can be displayed on the vacuum gauge display 130. The scale 126 can be calibrated based on the weight of the tank 110 to enable a user to review and understand the volume of liquid located within the tank 110. In some examples, a computing device may adjust one or more valves 120 based on the weight of the liquid in the tank 110 provided by the scale 126. For instance, the computing device may provide a signal to adjust a valve 120 (or automatically adjust the valve 120) in response to the weight of the liquid and the tank 110 surpassing a predefined threshold. The predefined threshold may depend on the destination thermal management system.

[0028] In addition, the connection 132 shown in Figure 1 is included to represent various types of interconnections between components within the system 100. As such, the connection 132 may include various types of tubes, hoses, wired and/or wireless connections, among others. In addition, gauges can be positioned at various points along the tubes/hoses to enable the pressure or other measurements to be displayed.

[0029] In other examples, the system 100 can use other components, different quantities of components, and other arrangements. For instance, the system 100 can also include a computing device 134, which can be communicate with one or more components of the system 100 via a wired or wireless connection. The computing device 134 can be used to adjust valves 120, the vacuum pump 114, and/or other components within the system 100. In other examples, a user may physically adjust the valves 120, the input 102, the vacuum pump 114 and/or other components within the system 100.

[0030] In addition to supplying a thermal management system with conditioned heat thermal fluid, the system 100 can also receive heat thermal fluid from the thermal management system. For instance, a spacecraft or another thermal management system application may drain used thermal fluid back into the system 100 via the output 116 or another receiving connection.

[0031] Figure 2 illustrates a device configuration diagram for conditioning and delivering heat transfer fluid, according to an example implementation. In the example configuration diagram, the device 200 includes components arranged to condition and supply liquid to a fluid system. In other examples, the arrangement of components can differ for the device 200. In addition, the configuration can include more or fewer components in other potential arrangements.

[0032] As shown in the example implementation, the device 200 includes an input 202 configured to couple to a container 204 of heat transfer fluid. The input 202 and the container 204 as well as other components are connected together via tubes 203, which can include various types of connections between components. The size and configuration of the tubes 203 can differ within examples. In some instances, the container 204 can be a transport drum of hydrocarbon liquid or can have another configuration in some cases.

[0033] The device 200 also includes a molecular sieve 206, which is configured to remove moisture from the heat transfer fluid. In practice, a pressure source 208 is configured to push the heat transfer fluid out of the container 204 and through the molecular sieve 206. To enable pressure and the heat transfer fluid to flow through components of the device 200, the device 200 includes multiple valves (i.e., valve 220A, valve 220B, valve 220C, valve 220D, valve 220E, valve 220F, valve 220G, valve 220H, valve 2201, valve 220J, valve 220K, valve 220L, valve 220M, valve 220N, valve 220O, valve 220P, valve 220Q, valve 220R, and valve 220S). For instance, opening valves 220A-220C and valve 220E may enable gas pressure to flow from the pressure source 208 and into the container 204 holding heat thermal fluid. The gas pressure from the pressure source 208 can push the heat thermal fluid into the device 200 via the input 202 and through the molecular sieve 206 when the valve 220H positioned in between the input 202 and the molecular sieve 206 is open. For instance, the pressure source 208 can be a tank holding an inert gas that can flow through the device 200 pending on the current states of valves 220A-220S.

[0034] In the example implementation shown in Figure 2, the device 200 further includes a filter 220 and a valve 220J is positioned between the molecular sieve 206 and the orifice 212. The filter 220 can further remove particles from the heat transfer fluid while the valve 220J can be used to limit the heat transfer fluid's access to the orifice 212. When the valve 220J is opened, the heat transfer fluid can flow through the molecular sieve 206 and the filter 222 before being separated into gas particles and liquid within the tank 210 by the orifice 212. To enable the separation of the heat transfer fluid within the tank 210, the tank 210 is connected to a vacuum 214. In the example, the vacuum 214 is able to remove gas particles from the tank and within the device 200 when a valve 220Q and a valve 220L are open. In addition, the vacuum 214 is coupled to a cold trap 218 that is configured to provide protection the vacuum 214 during operation. The cold trap 218 can be configured to prevent undesired materials from entering into the vacuum 214. For instance, the cold trap 218 can remove unwanted contaminants (e.g., water, solvents, acidic or alkaline compounds) from the gas stream or to prevent pump back streaming. These conditions can cause a loss of efficiency or damage when introduced into or emanating from the vacuum 214. In some examples, the cold trap 218 is a glass, tank, dry ice, vacuum cold trap vessel, or another configuration of cold trap.

[0035] As shown in Figure 2, the orifice 212 is included within the device 200 to separate the heat transfer fluid into liquid and gas particles within the tank 210 after removal of moisture from the heat transfer fluid by the molecular sieve 206. The size of the tank 210 can vary and may depend on the desired liquid supply required by the thermal management system coupled at the output 216. As such, the vacuum 214 can remove air and/or other gas particles from the tank 210 to enable the orifice 212 to separate the heat transfer fluid into the liquid and the gas particles within the tank 210.

[0036] The device 200 is further configured with an output 216, which is configured to supply the liquid into a fluid system. In practice, the pressure source 208 is configured to push the liquid out of the tank 210 and into the fluid system. The output 216 is configured to supply the liquid into the fluid system after removal of the gas particles by the vacuum 214. In some examples, the fluid system may be positioned on a spacecraft and can be configured to reduce the potential of bubbles being created in the spacecraft's propulsion system by using the liquid to slowly supply the propulsion system. The device 200 also includes pressure release valves 223 that can be used to release pressure produced by the pressure source 208 and pressure gauges 225 to indicate pressure within the device 200 relative to various components. The pressure gauges 225 allow a user to monitor the processes performed by the device 200, which also can signal if the user should open a pressure release valve 223 in some situations if pressure is too high.

[0037] The device 200 also includes a scale 224, which is positioned under the tank 210. The scale 224 can measure a weight of the tank 210 when the tank 210 includes liquid and subsequently display the weight of the tank 210 on a scale display 226 for the user or users to review. Similarly, the device 200 also includes a vacuum gauge display 228 configured to display a status of the vacuum 214.

[0038] As further shown, the device 200 includes a housing structure 230, which may further include wheels. The input 202, the molecular sieve 206, the pressure source 208, the orifice 212, the tank 210, the vacuum 214, the valves 220A-220S, the filters 222, and the output 216, among other components are positioned on and/or connected to the housing structure 230 to enable the device to change positions. The housing structure and wheels enable the device 200 to be moved to a position nearby the fluid system receiving the conditioned liquid produced by the device 200. The device 200 further includes a sample output 232. This enables liquid from the tank 210 to be obtained and sampled. The device also includes a drain connection 234 configured to connect to a drain to remove heat transfer fluid from the device 200.

[0039] Figure 3A depicts a device 300 for conditioning and delivering heat transfer fluid, according to an example implementation. The device 300 may represent a physical build of the device configuration diagram depicted in Figure 2 and/or the system 100 shown in Figure 1. In other examples, the device 300 may be a variation of the example devices and systems described herein.

[0040] As shown in Figure 3A, the device 300 includes an input 302 connected to a transport drum of hydrocarbon liquid 304. The device 300 also includes a tank 306 for receiving the hydrocarbon liquid after a molecular sieve removes moisture from the hydrocarbon liquid and an orifice 307 coupled to the tank 306 that can separate the hydrocarbon liquid into gas particles and liquid. The device 300 also includes the vacuum 308 coupled to the cold 310 and a scale 312 positioned under the tank 306. The device 300 includes housing 314 that is a cart that enables configuration of the different components of the device 300 for operations. As shown, the housing 314 includes wheels 316 to enable movement of the device 300.

[0041] Figure 3B depicts another view of the device 300 shown in Figure 3A. As shown in this view depicted in Figure 3B, the device 300 further includes a molecular sieve 317, valves 318, filters 320, gauges 322, displays 324, pressure gauges 328, pressure relief valves 330, and additional coupling points 332. The device 300 also includes an output 326 for supplying conditioned liquid to a thermal management system. The device 300 can also be configured to receive liquid from a thermal management system via the output 326 or another coupling component.

The type and quantity of filters can vary within examples.

[0049] Block 412 of the method 400 involves supplying, via an output, the liquid into the fluid system. The pressure source is configured to push the liquid out of the tank and into the fluid system. For the system 100, the pressure source 108 can push the liquid out of the tank 110 and into the fluid system via the output 116. In some instances, the liquid may be supplied to the fluid system once the tank accumulates a given volume of liquid in some examples. The given volume of liquid can depend on the fluid system. For instance, the fluid system can be part of a spacecraft that has specific liquid requirements.
